Which vaccine provides protection against Hepatitis B?

Engerix-B is a vaccine specifically designed to provide immunity against Hepatitis B, a viral infection that attacks the liver and can lead to chronic disease and increases the risk of liver cirrhosis and liver cancer. This vaccine contains hepatitis B surface antigen (HBsAg) and stimulates the body's immune response to produce antibodies against the virus, thereby protecting individuals from future infections.

The other options listed do not provide protection against Hepatitis B. Prevnar is a vaccine that protects against pneumococcal disease caused by Streptococcus pneumoniae; FluMist is a nasal spray vaccine used to prevent influenza; and Vaxneuvance is another pneumococcal conjugate vaccine targeting different strains of pneumococcus. Each of these vaccines is effective for their specific diseases but does not include protection against Hepatitis B, emphasizing the unique role of Engerix-B in public health for preventing Hepatitis B infections.
